If you don't have a version already, you can install GNU
libiconv (http://www.gnu.org/software/libiconv/).
+ * libintl, from GNU gettext (http://ww.gnu.org/software/gettext).
+ GNU libc includes an integrated libintl, so there is no need to
+ separately install libintl on a GNU/Linux system.

The following packages are required to enable PSPP's graphing
features. If you cannot arrange to install them, you must run
`configure' with --without-cairo.
